I don't know the intricacies of script includes or the other things mentioned above but when I build sites in dreamweaver that include javscript navigation menus I make the whole menu a library item that dreamwever will allow you to modify and update site-wide. This may not solve your absolute vs. relative links problem but I find it reduces my coding time immensely.
